| ABSTRACT |
|
The behaviour of a upflow anaerobic sludge bed filter (UBF) and a upflow anaerobic filter (UAF) treating a landfill leachate was investigated. The UBF and UAF treating the landfill leachate containing 10 g SCOD/L were successfully started up within a month through the control of upflow velocity, although the initial organic loading rate was high at 11.67 g SCOD/L ■ day. The maximum organic loading rate was 18.23 kg SCOD/m3 • day for the UBF and 14.12 kg SCOD/m3 • day for the UAF, determined by monitoring the SCOD removal, biogas production and bicarbonate alkalinity.
The SCOD removal efficiency for both reactors was over 90% during steady state except near the maximum organic loading rate. The trend of CH4production for the two processes was similar to the SCOD removal, and the maximum CH4 production was 0.24 L CH4/g COD for the UBF and 0.20 L CFWg COD for the UAF. The biomass yield of 0.398 g VSS/g COD in the UBF was higher than that in the UAF, and resulted in better for the UBF.
